Abstract
The invention relates to a method of determining an identifier of determined discriminating power from biometric data. According to the method, biometric data is obtained relating to an individual. The biometric data is converted into a digital string. A word of an error-correcting code is associated with the individual. The error-correcting code word is added to the digital string. An identifier relating to the individual is determined by applying a hashing function to the error-correcting code word, the hashing function being selected to ensure the determined discriminating power to said identifier.
